Respiratory diseases affect the airways and lungs, impacting breathing. Common types includeasthma, chronic obstructive pulmonary disease (COPD), bronchitis, pneumonia, and lungcancer. Infections like the flu and COVID-19 also fall into this category.

Symptoms vary based on the condition, but common ones include: Coughing (dry or with mucus) Shortness of breath Wheezing Chest pain or tightness Fatigue Difficulty breathing

Diagnosis usually involves: Medical history and physical exam Pulmonary function tests: To measure lung capacity and airflow. Imaging tests: Chest X-rays, CT scans, and MRI. Blood tests: To assess infection or oxygen levels. Sputum tests: To check for bacterial or viral infections.

Medications: Bronchodilators to relax airway muscles (e.g., for asthma and COPD). Corticosteroids to reduce inflammation. Antibiotics or antivirals for infections like pneumonia or the flu. Mucolytics to thin mucus. Oxygen therapy: For diseases that cause low oxygen levels, such as COPD. Inhalers: For conditions like asthma, providing rapid relief. Lifestyle changes: Quitting smoking, weight management, and avoiding allergens. Surgery: In severe cases, such as lung cancer or damaged lung tissue.

Quit smoking: Smoking is the leading cause of many respiratory conditions, including lungcancer and COPD. Avoid air pollutants: Limit exposure to secondhand smoke, dust, chemicals, and outdoor pollution. Get vaccinated: Vaccinations can prevent infections like the flu, COVID-19, and pneumonia. Practice good hygiene: Wash hands frequently, avoid touching the face, and use a mask incrowded places. Stay physically active: Regular exercise improves lung function and general health. Maintain a healthy weight: Obesity can worsen respiratory conditions by putting pressureonthe lungs
